other many theories:
theory 1: a depression to collect sediment or residual oil when changing.
this depression keeps stuff from falling of flowing into the engine when
you take the filter off.
theory 2: it's just something from the casting/machining i.e. to make it so
a machine can handle the part or something like that.
theory 3: subaru's future high end car has a sensor inside this depression
so that it can detect oil leak :]
theory 4: it is for a different kind of oil filter

Water heater前段时间叫plumber来修了一下loose的flue pipe.。就是water heater上
方的白管子。plumber割掉一小段松了的pipe,换上新的。说弄好了,不会有CO漏出来了
。这个loose flue pipe的问题是inspection时发现的。我们刚搬进这个房一个月。
现在的问题是water heater运行时老发出里面有异物撞击的声音,很象烘干机烘干衣服
时衣服在里面抛来抛去的声音。声音不小,我们在楼上都能听到。我pretty sure这个
声音在plumber修管子之前是没有的。打电话给plumber,他让我们把water heater的温
度调低点。我们调了,好像管用了一个晚上,第二天又有声音了。plumber说也许是
sediment的问题。可是这个噪音我很sure是修完管子后才有的。但是声音从tank里出来
,好像跟上面的pipe又没什么关系。
大家帮忙分析一下。需不需要找professional来看一下。
